Correct answer: (c) Flower bud
Explanation
- A
Terminal bud
A terminal bud sits at the tip of a stem and continues vegetative axis growth. A commercial clove is not that apical vegetative meristem.
- B
Accessory bud
An accessory (or extra-axillary) bud is an additional bud beside the main axillary bud. Clove spice is not classified as an accessory bud.
- C
Flower bud
A clove is the dried unopened flower bud of Syzygium aromaticum (family Myrtaceae). That botanical identity is the official key.
- D
Vegetative bud
A vegetative bud produces leaves or a shoot, not a flower. Clove is harvested as a floral bud before opening, so it is not a vegetative bud.
Summary. Official key is (c) flower bud. Cloves are picked just before the corolla opens and then dried; the spice is the calyx and unopened petals. Terminal and vegetative buds are shoot tips; accessory buds are extras in the leaf axil. Honour the stored letter (c).
